Measurements of identified hadron spectra are considered as an
important test of various non-perturbative models of hadron production
at high energies, as well as those of perturbative QCD
calculations. ALICE performs extensive studies of hadron production
due to its powerful particle identification capabilities
[1]}. Charged particles are identified by several
tracking detectors covering complimentary kinematic ranges. Barrel
tracking detectors are embedded into a solenoidal magnet with magnetic
field of 0.5 T. This is a relatively soft magnetic field which allows
to reconstruct charged tracks at transverse momenta starting from
\(p_{\rm t}>50\)  MeV/\(c\) . Inner Tracking System (ITS) and Time
Projection Chamber (TPC) can identify charged particles in the full
\(2\pi \)  azimuthal angle and pseudorapidity range \(|\eta |<0.9\) , via
measurements of their ionization loss \(dE/dx\) . Time-of-flight
measurements, provided by the TOF detector in the same solid
angle as ITS and TPC, can discriminate charged pions, kaons and
protons in a higher momentum range. The limited-acceptance High-Momentum
Particle Identification detector (HMPID) is a Cherenkov detector
covering a solid angle \(\Delta \phi =60^\circ \)  and \(|\eta |<0.6\)  is used
to identify charged particles at a higher momentum range, up to
\(p=5\)  GeV/\(c\) . Transition Radiation Detector (TRD) is another
barrel detector surrounding TPC, which is designed to identify
electrons and at present covers about a half of the complete azimuthal
angle.
